' .SANDING Device.

Specification of Letters Patent.

Patented .oct'as, 1906.

Application filed April 21. 1906. Serial No. 813,060.

In ordinary methods of preparing sand for.

track-sanding operations it is necessary to first dry the sand by tedious operations which materially increase the expense,'and

after the sand is dried it is placed in the sandboxes.

The present invention contemplates the drying of the 'sand within the box, or, in other words, the wet sand is placed directly in the reaches the bottom of the box, and while located in the bottom of the box it is still affected b drying-heat until it is used or dispensed t rough-the usual sanding-pipes.

The invention consists in the construction and arrangement of parts, which will be more fully hereinafter set forth. t

- In the drawings, Figure '1 is anelevation of a sanding-box embodying the features of the invention. Fig. 2 is a transverse vertical section on the line 2 2, 1.

rotary air-distributing pipe forming part of the improved sand-box.

Simr ar numerals of reference are employed to indicate corresponding parts in'th'e several views.

The numeral 1 designates a casi' ofthe.

usual form and construction of sand- 'oxes as now applied to locomotive-engines and is provide with suitable outlets or distributing-piges arranged as usual and connecting e bottom of the casing 1. The top of the casing 1 has an inlet-cover 2, by means of which sand may be introduced into the with t v Fig. 3 is ahorizontal section taken in the lane of the line 3 3, Fig. 2. Fig. 4 is a detai 'view of the supply connection 6 at one end which is 10- member- 4. I The tubular member 4 has a cated exterior of the casing-1 and an outlet steam used may be taken from any part of the locomotive, and it is proposed in some instances to use the exhaust-steam, which may be conveyed to the connection 6 of the mem her 4 by any suitable pipe means. Immediately above the screen 3 is a rotary air-disconnection 7 at the opposite end.- The tributing pipe 8, having a slit orlongitudinal o ening 9extending over the entire length 1: ereof within the casing .1. This air-distributing pipe may be rotated by any suitable meanssuch, for instance, as gears -1O, actuated b motive. his pipe is operated to cause the slit or longitudinal opemng 9 therein to semicircularly sweep the interior of the box.

In the o eration of the device wet sand is placed in t e casing above the screen 3 and over the air-distributing pipe 8. Steam is admitted to the member 4 and circulates through the tubular arms 5 and effectively a rod 11 from the cab of a 1000- to the outletof the air,v from said pipe is avoided and is materially advantageous in.

.view 0: the ordinary perforate stationary pipe construction which simply blows holes intoportions of the sand without operating on the entire body of sand, as will result by the operation of the ipe8. The-dry sand passes or sifts throug the screen 3, and all grit or other clogging substances that may be therein are prevented from assi .downwardly into the bottom of t e cas1ng,-' and therefore obstruction of the delivery or dispensing pipes is obviated.

By providing a box to receive the wet sand and to the latter and prepare it foruse is a material savin in labor, time, andexpense as com ared wit the ordinary methods now.

ursu

oxes on locomotives and other devices, and the additional cost to construct ,the imroved sand-box relatively to the common lbrm of box is a small consideration when com and to the expense of ordinary met ods now employed to prepare sand prior to the opplicat-ion thereof to a sand-box.

in preparing sand for use in sand- Ild Having thus frilly described "the invention, what is claimed as new is- 1. A sand-box of the class set forth having a rotary airdistributing pipe therein.

2. A sand-box of the class set forth having.

a rotary air-distributing pipe disposed'horizontally' therein.

3. A sand-box of the class set forthpro vided with heatin means, and a rotary airdistributing pipe t erein.

4. A sand-box ofthe. class set forth: provided with heating means, and a rotary airdistribntingpipedisposed therein and having eating means.

posed. screen-therein, and a rotary air-distributing pipe disposed over and adjacent to the screen.

8. A sand-box having a heating means comprising a tubular member with tubular arms extendin outwardly from opposite ortions thereo and a screen above the said 35 9. A sand-box having a heating means therein comprising a diametrically arranged tubular member withtubular arms extending outwardly-from opposite portions therein.-

10.- Asand-box of the class set forth having 40 a. horizontal screen therein, a heating means arran ed below and close to the screen and provided with a tubular member and tubular arms extending from oppositeportions of the latter, and a rotary air-distributing pipe dis- 4 5 posedtover the screen and. extending diametrically ofthe casing.
